Abstract:
Novel processes for producing enantiomerically enriched and enantiomerically pure compositions of 2-acyl substituted chromane compounds, and 2-acylchromane compounds that are intermediates for producing platelet aggregation inhibitors and/or are themselves potent platelet aggregation inhibitors are disclosed. Further disclosed are processes for producing salts such as acid addition salts for such enantiomerically enriched compositions.
